I have completed the lesson that mirkocurtolo posted the link to in post #17.
The modified code is working.
It would be nice if the template page mentioned that it was to be used in a lesson, and wasn't of use until modified.
At the beginning of the lesson it suggests it will take 45 mins to complete.
It took me 1 hour and 45 minutes, I'm sure a new user would take even longer.
I noticed a few errors/omissions in the instructions regarding modifying the code.
Such as the wrong line being highlighted (it is the line above that should have been highlighted) :
Also lines 154 to 158 needed to be added:
but lines 154 - 158 was not highlighted in the section showing the modifications required:
Without those lines being added, the Modulino Knob would not highlight the day at all on the Modulino Pixels.
